In recent years, with the spread of various sensors and improvements in processing techniques, those sensors and processing techniques have been used for railway measurement. Railroads are heavy equipment industries with vast facilities, and they spend a lot of money and money on maintenance. For this reason, in order to accurately judge the necessity of maintenance, etc., it is indispensable to monitor the state of the equipment and measure quantitative data such as train sway.

[0003] Regarding inspection and measurement (inspection and inspection) of railways, track inspection vehicles that are large and run independently on railways have been introduced.
Condition monitoring by regular measurement is implemented. However, although current track inspection vehicles have high performance, they are expensive and their operation is limited. Therefore, an inspection system that is economical and has necessary and sufficient accuracy that can be mounted on a commercial vehicle or a maintenance vehicle such as a passenger train or a freight train has been developed. In this inspection system, the control of the measuring device mounted on the train must be operated on the train. Also,

As described above, in order to control the measuring instrument, it is necessary to operate on a vehicle, and an operator is required for the operation. Also,
Since monitoring of the measurement data is also performed on the vehicle, an operator and a monitor are required, and a space for the operator and the like is required. Therefore, it is often difficult to permanently install a measuring instrument in a business vehicle or a maintenance vehicle where there is no room for space. For this reason, it is necessary to perform many important measurements with a dedicated vehicle such as a track inspection vehicle, or to connect a special vehicle to a commercial vehicle, and to carry many equipment and operators into the vehicle.

Accordingly, it is an object of the present invention to provide a train measurement system without an operator, which can control a measuring device mounted on a train from a remote place and can monitor the measuring device at a remote place.
